SPECIFICATION forming part `of Letters Patent No. 489,144, dated January 3, 1893. Application iiltl Tune 7,1892. Serial No. 435,820. (No modell.)

To' a/ZZ whom t 11i/(ty concern:

Be it known that we, 1to1-mon It. lnowN, residing at Chicago, in the county of Cook and `State of Illinois, and LEE DE CAMP, of 5 Denver,in the county of Arapahoe and State of Colorado, both citizens of the United Sta-tes, have invented certain new and useful lmprovements in Comlensing- Chambers for Lead Fumes, as set forth in the accompanyxo ing drawings, forming part of this specification, vin which" Figure 1, is a vertical sectional view ot a condensing chamber embodying our invention. Fig. 2, is a horizontal sectional viewof I5 the same on the line i12-gn of Fig. l. Fig. 3, is a longitudinal sectional view on the line ro-fw ot hig. l.

Our invention relates lo means for collecting and utilizing waste lead fumes, and it con( sists of the constructions and combinations ol devices which we shall hereinafter fully dcscribe and claim.

To enable others skilled in the art to which our invention appertains to make and use the same wc will now describe its construction and indicate the manner in which the same is carried out.

'lhe structure or condenser A is composed preferably of brick or storie and is divided 3o into any desired nu mbcr of rooms, compartments, or stalls A by means of vertically disposed partitions C, each of which extends from the floor or base to or near the top of the structure and has its lower portion formed or provided with a hollow space or passage C communicating at one end with a vertical stack or fiue D, whereby a constant circulation of air is maintained in the bases of the partitions to prevent the walls thereof becom- 40 ing overheated by the accumulating dusts from the smelters.

In the partitions C openings d are made to connect each chamber or room with the stack, said openings being closed and controlled by any well known forrn of damper CZ.

t, The gases from the furnaces are conducted to the condenser through a pipe or flue E, and are admitted to the condensing chambers through the connecting pipes E as shown in 5o .Fig 2, said pipes E being closed at their outer ends by means of hinged or swinging doors e, operated by handles or rods c extendingr outwardly beyond the pipe or tine E so that the said doors may be convenientlyoperated from the outside. A

The ceilings L of the chambers are coinposcd of textile fabric secured in position by suitable sustaining frames, and they are made ^shaped in cross-section to give the greatest area of straining surface through which the 6o gases conducted to the chambers are forced, whereby the mechanicalparticles in the fumes are collected for future treatment.

'lhe ceilings are preferably made of wooden or other frames covered with muslin or other textile fabric, and arranged in any well known manner so that they may be readily removed when desired, said ceiling being designed to com pletelycoverand form a root' for the chambers.

Suitably journaled and extending longitudinally through the structure, and located either hbove or below the apex ofthe ceilings, are shafts Il composed preferably of hollow piping, and having their ends projecting beyoud the end walls of the structure and provided with levers or cranksfor imparting an oscillating motion to the shafts; and to these shafts are secured the downwardly depending arms or bars F which serve as beaters. 8o From this arrangement it will be seen that when the shafts are oscillated, these beaters strike the inner converging walls of the ceiling and by this jarring action dislodge the dust accumulating upon the fabric, whereby the material composing the ceiling is prevented from becoming clogged up, while the necessity for entering the rooms or chambers for the purpose of shaking down the dust is entirely obviated, as thebeaters are operated 9o from the exterior of the structure.

In the space above the ceiling platforms G are made to enable the attendant orworkman passing through the upper portion of the structure for the purpose of removing or re- 95 pairing the ceiling or its frames. The gases which pass through the fabric ceiling and enter the space above, pass into the open air through the usual roof ventilators I, or they may be otherwise disposed of it' desired.

loo

is left open to admit fresh air to assist com-- on, substantially as herein described.

shown, and are discharged in a partially cool vor more of the rooms or chambers, the damcause the arms or boaters to In practice a condensing chamber would be erected some distance from the ore furnace' to which it would be connected by pipes or ues, and the gases from said furnace are drawn through these {lues or pipes by means of snitable exhaust or Ventilating fans, not

condition into the rooms or chambers in thc manner before described. v

The sublimed leadandn other particles of minerals and unconsumed carbon are deposited'on the floor of the rooms or chambers A, only the lighter portions arising to the top with the gases, where they are collected by the fabric ceilings. 'When asuilicient amount of deposit has been accumulated in any one per e of said chamber or chambers is closed and the damper d is opened. The accumulated dust is then fired through the doorl leading to the room or chamber, which door bustion. All of the smoke caused by the burningv carbon in the collected' dust then passes out of the chamber or room into the stackD and. thence into the air. \Vhen the accumulated dust is all charred, it is wheeled out or otherwise removed, and sent to the furnace to be reduced toa n'ietallic state and the door l closed, the damper e being again opened to admit thc gases from the furnace'.

llaving thus described our invent-ion, what we claim as new and desire to secure by Letters Patent, isrf- Y Y Y l. In a condenser, a condensing chamber cr l room for receiving the gases from the furnace, said chamber having a ceiling composed of fabric, in combination with shafts located con,- ltiguous to said ceiling and provided with arms or beaters adapted to strike against said ceiling and dislodge the accumulated dustthercin a condenser for lead ores adapted to receive the gases from the ore furnace, the ceilings of the condensing chambers composed of fabric and `having converging sides, in combination with shafts extending through the condenser andy located under the apex of the ceiling, beaters or arms depending from the shafts, and means for oscillating the shafts to strike the sides lcarbon from the accumulated dust of the ceiling and dislodge the accumulating dust, substantially as herein described.

In a condenser, the condensing chambers having division Walls or partitions between them,and means foradmitting the gases from the furnace to said chambers, in combination with ceilings of textile fabric in the upper portions of the chambers and made of an in verted V shape incross-scction shafts`extendiugthrough said condenser justbelow the apex of said ceilings and having their ends extended beyond the exterior of the condenser, and arms or beaters on shafts adapted to strike against the walls of the ceiling when the shafts are oscillatcd whereby the accnmnl lated dust is dislodged and `the fabric ecm posing the ceilingI cieancd, substantially as herein described.

e. In a condenser, the partiti-anis dividing the condenser into separate ringnns or cham bers, and having their lower tions hohen' to form tlues or pas 'th the main flue or st: c the dampercontrolled op( ii 'which the gases caused h) iurning nt the may es tiall-y cape to the main tine or stach, snbstan as herein described.

in a condenser, the combinal'itm rooms or compartments with intcrvt titions having air spaces or passages in heir lower portions, danipei-controlled openings in thesides ofthe partitions for connecting each room with the flue or stack, thc dampercontroled inlet ilucs or pipes E from. the furnace llue7 the ceilings of fabric having converging sides, and the shafts in said ceiling provided with arins'or beaters for operating against said sides, said shafts having their ends extended beyond the exteriorof thc condenser so that the arms or beaters are actu-- ated from the out-side, substantially as herein described
